Main Body

[Factors Responsible]

Natural -

1Liquefaction & earthquake, losening of soil.
2Under cutting by rivers -> erosion.
3Isostatic stabilization of earth (tectonic plate movement).
4Underlying rock characteristics (limestone).

Anthropogenic -

1Unsustainable mining (nos/mil -mal stoichitr).
2Unvetted development (development of tunnel in geology).
3Rise in Renewal (keeling ground walk).

# Impact ---> (1) Life and livelihood at [Woshimpath], (2) loss of land (degradation), (3) misguides of people.

[MEASURES - NEEDED] - while natural factors are hard to control, but their vulnerability could be reduced.

-Unified Geological survey (Geophysical and civil engineering techniques (Japan's Tusuke system)).

(A) For manmade -->

-Responsible development - with adequate rehabilitative relocation (MMDR act 2015), afforest ation.

-Scientific mining with profess Roof control e.g. Langwad Cavity.

-Checking Borwell's.

In this context, Mishra Committee and Gaddi Committee recommends to be filled with mitigations view NDMA guidelines.
